Here, when the reflector temperature tc changes, the radiant input energy and radiant energy change, and the air heat transfer energy changes as the ambient temperature ta changes.The heat capacity of the photosensitive material depends on the thickness of the photosensitive material. The heat of evaporation depends on the moisture content of the photosensitive material.
